The results showed that with the increase of temperature and pressure,a considerable amount of original cementite formed within 20 seconds after the iron-based catalyst melted completely,and the carbon solubility reached a maximum saturation.
利用扫描电子显微镜观察了不同合成时间的金刚石合成效果以及相应触媒的组织结构,结果表明:随着压力、温度的升高,铁基触媒全部熔化为液态后约20秒内,熔体对碳的溶解度可达到极大的过饱和程度,生成数量极大的初生渗碳体,同时,金刚石单晶在这种环境中生成。
The results showed that more original cementite in catalyst at room temperature and atmosphere pressure corresponds to better quality and higher yield of diamond, whereas poor quality and lower yield of diamond corresponds to less original cementite in it.
结果表明,组织中有较多的初生渗碳体时,金刚石的质量好,产量高;反之,则质量差,数量少。
